The pneumatic motor of the pneumatic diaphragm pump converts the pressure energy of compressed air into mechanical energy and realizes continuous delivery of liquid by driving the diaphragm pump plate. This device has the advantages of high efficiency and reliability, wide range of application, and easy maintenance, and plays an important role in industrial production.

Pneumatic diaphragm pumps have an important position in the field of fluid transportation due to their simple structure, convenient operation, strong self-priming ability, strong corrosion resistance, etc. However, different industrial occasions have different performance requirements for pneumatic diaphragm pumps, so the reasonable selection of component materials has become the key.

As a common liquid conveying equipment in modern industry, the stable operation of pneumatic diaphragm pumps is of great significance to production efficiency. However, pneumatic diaphragm pumps often encounter the problem of being unable to pump out liquid in actual use, which not only affects production efficiency, but may also cause damage to the equipment. Therefore, this article aims to explore the reasons why the pneumatic diaphragm pump cannot pump liquid and propose corresponding solutions.

Pneumatic diaphragm pumps are placed in various special occasions to pump various media that conventional pumps cannot pump, and have achieved satisfactory results. In the process of using various series of pneumatic diaphragm pumps, we occasionally encounter the phenomenon that the pneumatic diaphragm pump suddenly crashes and does not work. This article introduces the reasons why the pneumatic diaphragm pump does not work.

Pneumatic diaphragm pumps and screw pumps are both positive displacement pumps. Pneumatic diaphragm pumps are pneumatic and do not produce sparks. Screw pumps are generally electric. The principle of both is the same. They both form a movable closed space to reduce the standard volume of fluid before the pump and increase after the pump, thereby increasing the pressure in front of the pump and reducing the pressure after the pump. Pneumatic diaphragm pumps are a very commonly used conveying machinery and equipment, and are recognized and trusted by the industry. People often confuse pneumatic diaphragm pumps and screw pumps. People confuse the two because they have the same characteristics, but in fact they are also very different.
